MILK BOTTLE.

Application led February 1,1, 1927. Serial No. 167,448.

This invention relates more especially to means for promoting the preventing of contamination of milk.

Milk is peculiarly subject to contamination by dirt, and germs carried by dirt, and it is therefore of great importance in the interest of public health that every measure possible be taken to preclude access of germs or dirt thereto. As far as my observation extends it is now customary to deliver milk to the consumer in bottles provided with a specially prepared paper cap sprung into a seat, recess or rabbet around the interior side of the mouth of the bottle; but because such a cap when seated lies entirely below the plane of the upper rim of the mouth of the bottle there is formed around the junction of the cap with the mouth a corner into which dust and other forms of dirt collects, it being diiicult, if not impossible, to remove such dirtv from such corner even though particular pains are taken to do so. When such a cap is employed more or less of the dirt isA quite likely to break volf and fall into the milk when the' cap is lifted out.

The object of the present invention therefore is to provide a construction whereby the upper surface of the cap coincides with or projects slightly above the inlet to the bottle;

vtap to make a firm and more diicultly peneand to adapt the invention to the vast number of bottles of the sort now in use so that they may be still utilized.

The invention is embodied in the example herein shown and described the features of novelty being finally claimed.

In the accompanying drawing- Figure 1 is aside View of an ordinary milk bottle with the neck and mouth in section showing my invention applied thereto.

Fig. 2 is a top plan view of a metallic .crown or cap-receiving member spread out and before application to the mouth of the bottle. v

Fig. 3 isa side View of the neck and li of the bottle showing the'member shown in ig. 2 applied thereto. l

In the views 5 designates the bottle 'which (i is of the ordinary form with the usual rabbet 6 aroundv the inner side of the mouthl or lip thereof. v

The crown member is preferably stamped or pressed in generally circular form `out of' I a sheet of suitable metal with a central open.- ing4 7 having a downwardly extending lip 8A to enter and fill the usual rabbet around the mouth of the bottle and an upwardly extending lip 9 annularly oil'set from the inner wall of said downwardly extending lip. Extendmg from the central ring-like portion'of the member are petal-'like portions 10 each having its sides cut so-that when they are bent down around the exterior of the lip of the bottle from a position shown by broken lines Fig. 1 they close substantially together with their edges meeting as shown in Fig. 3 thereby forming a continuous armor substantially confinlng the lip at its exterior side. The

petal-livke portions 10 are bent inward at the outer ends to hugat the'lower ends the wall of the lip near its base and said ends can be beaded or thickened as shownat 11 so that when pressed home a slight space is left between the petal-like portions and the lip to permit a cushion edect when the crown piece is subjected to blows on the side due to rough handling of the bottles. From the upper edge of the upwardly extending lip 9 of the central portion the crown slopes constantly downward and away from the inlet to the bottle. The character 12 designates the paper cap which can be of the usual form; The vertical wall of the seat can be'formed with a slight circumambient grooving as shown in F ig. 1 so as to bite into the rim" of the paper trable'j oint of the c'ap with the seat.

The crown piece can be applied to the bottle while hot, it shrinking into firm contact with the bottle upon cooling, and in some in stances the crown may be first bent to the requirpd form and sprung into position on the corners into which the dirt and dust is carried the wiping operation.

It will be further observed that the crown piece becomes a permanentport'ion of the bottle and forms an armor to'prevent breaking of the glass at the mouth of the'bottle.

The forms of the parts can be changed without departing from vthe gist of the vention as claimed.

vWhat I claim is:

1.l' A milk bottle having a metallic with` a central'openinlg, a cap seat around said opening at its-upper side and a paper cap seated therein having its upper portion flushing with the inlet to the bottle.

2. A milk bottle having a metallic armor with a central opening, a cap seat around said opening at its upper side and a. paper cap seated therein having its upper portion flushing with the inlet to the bottle, the external surfaces of the bottle around and adjacent to said cap seat sloping at all points. 10

downward away from said seat.

3. An armor for lthe lip of a milk bottle containing a central opening with a cap seat therearound'atvits upper side and petal-like portions bent into edgewise coincidence with one another andto embrace and entirely enclose the exterior of the lip.
